Honestly very fun despite it being a bit buggy. I loved the art style, and I liked the metroidvania mechanics.
The grapple was a super cool ability to unlock. I also really liked the story and felt like the world had a real vibe going for it. The sound design was very satisfying. It was never hard to figure out what to do because the art was super clear, and in general everything that needed to feel good felt good.
As for feedback, (ignoring the bugs because it is clear you were aware of them, and none of them were particularly significant) I think the time/traversal required between the items might be a tad too long. Like I get that they need to be longer to add tension with the timer but both might have benefited from being slightly shorter.
Overall really cool game. I played all the way to the end because i found it solidly engaging.
Fantastic work.
